The Huckleberry Island unit of the Lake Marion Preserve is near my house (Davenport/Haines City area), as is the Osprey Unit of the Hiloche Preserve. I have ONLY hiked nude in both areas, and they are well suited for that. Hiloche offers hike-thru potential if you leave a vehicle at each end, and there are several geocaches in the area if you're into geocaching.
I am off work that day, so I should be available.
Seminole county is one of four counties in the state where simple nudity is a crime in and of itself even with no lewd bahavior involved. They also treat it like a sex crime. I would not recommend hiking ANY seminole county trails nude.
On Saturday, 6/22, various members of three Southern Californian clubs (SCNA from LA, NitOC from Orange County, and the Camping Bares from SD) will hike down to Deep Creek Hot Springs in Apple Valley. Those who wish to, will camp overnight at Bowen Ranch and head back down to the springs on Sunday. If you're in the area come and join us, whether you want to hike down one day, or stay overnight and enjoy both days naturally!
